The Celestron Aluminum Dew Shield with Cover Cap serves as an indispensable accessory for safeguarding your telescope tube during field observations. This dew shield plays a pivotal role by minimizing the effect of radiative cooling on the Schmidt corrector lens, effectively preventing dew formation on the lens by keeping it below the dew point for an extended period. Furthermore, this Aluminum Dew Shield enhances image contrast by effectively blocking stray light from entering the telescope, thereby enhancing the quality of your viewing and astroimaging experiences. Rest assured, the Aluminum Dew Shield is tailored to fit your 11” EdgeHD, RASA, or Schmidt Cassegrain (manufactured after 2006) telescope tube precisely, ensuring optimal performance for your specific instrument.

Construction:

The Aluminum Dew Shield boasts a meticulous design, providing a perfect and custom fit for 11” Celestron telescope tubes. Its exterior consists of a robust, unyielding aluminum cylinder, ensuring it maintains its shape without folding, flexing, or deformation. Internally, the dew shield features a velvety lining, absorbing any residual stray light and excess moisture, thereby optimizing contrast during your viewing and imaging sessions. To secure the dew shield onto your telescope tube, utilize the two adjustable clips to ensure a snug and secure fit.

Additionally, the cover cap accompanying the dew shield is crafted from durable yet lightweight aluminum. When your telescope is not in use, simply place the cover cap onto the dew shield to shield your Schmidt corrector from stray dust particles. This cover cap also facilitates the quick and hassle-free acquisition of dark frames for imaging purposes.

For those astroimagers who employ the Fastar/Hyperstar configuration or utilize the RASA, you'll appreciate the integrated cable management slot at the base of the Aluminum Dew Shield. This feature simplifies and streamlines your setup by offering a convenient means to manage essential cables, such as those for our Dew Heater rings, without the risk of light pollution intrusion. Additionally, the dew shield incorporates cutouts to accommodate dovetail rails on both the top and bottom of the telescope tube, ensuring compatibility regardless of your configuration.

Enhance Your Setup:

When you acquire this item, you will receive two adhesive Celestron logo labels that you can apply to your dew shield or any other preferred location.

For an optimized dew-free night of observing and imaging, consider exploring the 11” Dew Heater ring and the Smart Dew Heater and Power Controllers as valuable additions to your setup.
